BRAKE-APPLYING MECHANISM.

Specification of Letters Patent.

Patented Dec. 15, 1914.

Application filed January 23, 1914. Serial No. 813,993.

To all whom it may concern Be it known that I, GUY H. VVoo'rnN, citizen of the United States, residing at Ford, in the county of Ford and State of Kansas, have invented certain new and useful Improvements in Brake-Applying Mechanism, of which the following is a specification.

This invention relates to vehicle brakes, more particularly to the class of brakes for attachments to hay racks, header barges, and like vehicles, and has for one of its objects to improve the construction and increase the efficiency and utility of devices of this character.

Another object of the invention is to provide a simply constructed device which may be applied to vehicles of various forms and structures without structural change in the vehicle and without material structural change in the brake mechanism.

Another object of the invention is to provide a simply constructed device which may be applied to a vehicle and operative from any point upon the vehicle or upon the load carried by the vehicle.

Another object of the invention is to provide a simply constructed device which may be so applied to the vehicle that it will not be engaged by the forward wheels after the latter are cramped in turning.

\Vith these and other objects in view the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims; and in the drawings illustrative of the preferred embodiment of the invention Figure 1 is a side elevation of a portion of a rack and a portion of a running gear of a vehicle with the improvement applied. Fig. 2 is a plan view of the portion shown in Fig. '1. Fig. 3 is a transverse section enlarged on the line 33 of Fig. 1. Fig. i is an enlarged perspective view of the rear transmission lever. Fig. 5 is an enlarged perspective view of the forward transmission lever. Fig. 6 is an enlarged perspective view of the link, which couples the transmission lever. Fig. 7 is an enlarged perspective view of the operating lever bracket.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The brake levers for hay racks and like vehicles are generally disposed externally of one of the side members 10 of the rack, as shown at 32, and near the rear wheel and axle, while the forward wheels are generally arranged to cramp against the side member at the forward end of the rack. Hence it is necessary to so arrange the connecting means between the brake lever and the op erating lever that the requisite motion can be transmitted from the operating lever to the brake lever without interfering with the cramping action of the forward wheels and without an abnormal or unnecessarily long throw of the operating lever. In the present invention these desired results are accomplished by arranging a plurality of transmission levers between the operating lever and the brake lever and partly outside and partly inside the side member 10 of the vehicle body, so that the forward portion of the exterior of the rack is left unobstructed for the action of the forward wheels when cramping. The pivots of the transmission levers are also so arranged that the requisite throw of the brake lever is accomplished without abnormal movement of the operating lever.

For the purpose of illustration the improved device is shown applied to a conventional hay rack, but it will be understood that the device is not necessarily lim ited to use upon a hay rack, but may be adapted without material structural change to similar vehicles, such as header barges and the like.

In the drawings, one of the side members of the rack is represented at 10, the transverse supports at 11 and one of the rails of the laterally directed rack members at 12. A portion of one of the rear wheels is represented at 13 with a bolster represented at 14: to support the rack member. The improved device embodies two flat plates 15-16 bearing upon opposite sides of the member 10 and secured in place by a transverse bolt or like fastening device 17. Mounted to swing at 18 upon the bearing plates 15 is a lever device which for the purpose of this description is called rear transmission lever, and comprises an outer portion 19 and an inner portion 22 united at their lower ends as at 21 and with a lateral offset 20, the portion 19 bearing on the outer plate 15 and the portion 22 bearing upon the inner plate 16. The two portions 19 and 22 scription is called the forward transmission lever. The pivot 23 is disposed intermediate the ends of the rear transmission lever 24, as shown. The brake beam is represented conventionally at 25 and carries the brake shoes, one of which is represented at 26. The beam 25 is suspended from the body by flexible devices such as chains, one of which is shown at 27.

Mounted for rotation upon the rear hounds, indicated at 28, is a rock shaft 29 having ,a relatively short depending arm 30 coupled to the brake beam by a rod 31. At one end the shaft 29 is extended into a relatively long arm 32. Pivoted at 33 to the vertical arm 32 is a tubular member 34, while another tubular member 35 is pivoted at 36 to the upper end of the portion 19' the rear transmission lever. The tubular member 34 is slidably disposed in the tubular member 35, the latter being provided with a plurality of apertures 3'? which register with a plurality of similar apertures in the member 34, one/or more clamp bolts 38 or similar devices being disposed through the ber 35 is provided with a registering apertures.

and increased or decreased in length within the range of the registering apertures as will be obvious. The rod 34 is likewise provided with a plurality of apertures 39 to receive the pivot member 33, while the tubular memplurality of apertures '40 to receive the pivot pin 36. By this means the length of the coupled rods may be adjusted longitudinally to any required extent within the range of the various apertures.

At their lower ends the transmission levers 19-24 are coupled by a link device preferably formed of bars 41, the two parts of the latter bar bearing at one of the opposite sides of the forward transmission the reartransmission lever and pivoted respectively thereto, as represented at 42-43. The rear transmission lever 1922 is provided with a plurality of apertures '44 spaced apart through one of which the pin 42 extends. By this arrangement the link members 41 may be adjusted upon the rear trans- 'member 10 is another plate 48 secured by By this means the members 34 35 may be adjustably coupled deflection under strain. a 7

It will be noted that a portion of the operlever and between the members 19- 22 of the same bolts 47 'Pivoted at 49 between the spaced members -46 is an operating lever arm 50 having a plurality of spaced apertures 51 at its lower end. At its upper end the member 50 is formed preferably tu crease the leverage.

Pivoted at 54 to the upper end of the forward transmission'lever 24 is a rod 55, while a tubular rod56 is pivoted at 57 to the lower endof the lever arm 50; The rod is slidably engaged in the tubular member 56, and the latter is provided witha plu- The rod- 55 is'provided with a plurality of apertures 60 to receive the pivot pin 54, and thus provide for the longitudinal adjustment of the rod relative to the member 24. A spring 61 is coupled to the lever arm 50 to hold the device yieldablyin'itsforward position. I

By arranging the rods 3435 and 55'56 to be longitudinally adjusted the improved device may be "readily adapted'to racks of varying lengths, and by increasing or decreasing the lengths of the rods this variation may be correspondingly increased. By providing an extension handle 53 the brake mechanism may be actuated from the top of the load upon the vehicle, as for instance upon a load of hay, alfalfa, or thelike.

The tubular member 34 is curved to enable it to pass beneath the adjacent cross beam 11, and is provided'with a supporting core, represented at 62, and preferably of bent wood, to reinforce the member and prevent ating mechanism is externally of the rack member 10, while the remaining portion is arranged internally of the member 10, so

that the strain is applied from opposite sides of the rack member.
